FRANK J. SOMERVILLE, OF MONTREAL, QUEBEC, CANAD Assreivoa T IMP RIAL -roEAoco COMPANY 0E CANADA LIMITED, or MONTREAL, QUEBEC, CANADA CIGAR H AD KNURLING AND EUNCEING EVIC Application file d J'une 10,

- This invention relates to the manufacture of cigars and compr ses a clgar head knurlmg and punchlng device for producing c1- gars of the kind described in my co-pending said application, the portion of the wrapper,

,which is penetrated by the punch is turned Or tucked into the outer end of the bore formed in the filler-inorder to'secure this end ofthe wrapper against unravelling and to prevent contact of the tongue with rugged edges ofthe wrapper or that portion of the filler that would otherwise be-exposed at the outer end of the bore.

A The object of the present invention is to provide means whereby the punching of the bore and the turning ofthe wrapper into the outer end of the bore may be conveniently accomplished in a single-operation.

.The essential featureof the invention consists in attaching a punch to a cigar head knurling device of substantially conventional form. When the end of the cigar is inserted in the knurling device to firm up and finish olfthe wrapper covering this end of the cigar, the punch pierces the wrapper and penetrates the filler to form a bore of the size and length dependent upon the type of punch used for this purpose. .The punch is preferably made of tapering construction so that'as it penetrates the filler it causes the portions of the wrapper surrounding the opening initially made therein by the point of thepunch to be turned or tucked into the outer end of the bore which is beingformed in the filler so .that, in the finished cigar,

there is no exposure of the filler at the-outer end of the bore.

Proceeding now to a more detailed description of the invention, reference will-be had to the accompanying drawings, where- V p 5 Figure 1 is a top plan view of a cigar head 1932. Serial mQciesos.

g and punching apparatus provided in accordance with this invention.

Figure 2 is a side view of said apparatus. Figure 3 is an end view of said apparatus. Figure 4 is a view partly in longitudinal section and partly in elevation of the combined knurling and punching head forming part of said apparatus.

Figure 5 is a fragmentary view of a cigar knurlin produced in accordance with this'invention;

Referring more particularly to the draw ings, 11 designates a horizontal bearing sleeve formed at the upper end of a standard 12 rising from a" suitable base-'13, said bearing sleeve containing a bushing 14 held in place by a set screw 15 and a lock nut 1'6. A shaft 17' is rotatably mounted inthe bushing 14: with the ends of the shaft projecting-beyond corresponding endsof the bearing sleeve 11. One end of shaft 17 carries a driving pulley 18 keyed or otherwise suitably fixed thereto. The'other end of said shaft carries a knurling head of the'usual type including a ring 19, a spindle 20, and the usual arrangement of curved knurling arms 21. As herein shown,

1 the spindle 20 is fixed in a bore 22 formed in the lastmentioned end of the shaft 17 so as to rotate with said shaft when power is applied. to the pulley '18. The punch provided in accordance with this invention is indicated at 23 and hasone end fixed in a bore 24 formed in the outer end of the knurling head spindle 20. The pointed-end of the punch terminates short of the ring 19 and is centered with respect to the ring and curved knurling arms 21. I

The end of the bushing remote from the driving pulley is extended beyond the corre sponding end of the bearingsleeve 11 to provide a support for a U-shaped member 26. One arm 27 of this memberjisformed to pro vide a horizontal cigar support 28 having its upper surface transversely'curved'as indiduring the knurling and punching operation by a displaceable cigar guiding and centering member indicated at 35. As herein shown, said member comprises a tube open at both ends and having one end formed to provide a flange 36 and a pair of supporting arms 37 and 38 of unequal length. These arms 37 and 38 are pivoted as indicated at 39 to the side members of the clamp 31 so as to permitthe member 35 to be swung from the horizontal position shown in'full lines in Fig. 2 to the vertical position shown in dotted lines. The long arm 38 is provided'near its free end with an opening 40 adapted, in the horizon tal position of the member 35, to register with asocket 41 formed in the bearing sleeve 11 so that a locking pin 42 may be passed through the arm into said socket to secure the member 35 in its horizontal position.

, At the end remote from the flange 36 the member 35 has its lower portion cut away to providea notch 35a receiving the inner end of the horizontal cigar support28-sothat the lower wall of the bore formed in said member is thus aligned with the curved surface 29 of the'cigar support. 7

In the operation of the apparatus described herein, the cigar supporting and centering member 35 is secured in the position shown in Fig. 2 and a driving belt connected to the pulley 18 to impart rotation to the shaft 17 and to the knurling and punching head fixed to said shaft. A cigar 44: is then'placed on the support 28 as shown in Fig; 2 with the head or end of the cigar which is to be placed in the mouth inserted within the .tubular guide and centering member 35. The'cigar is then pushed throught the member 35 into engagement with the knurling arms 21 which perform the usual knurling operation on the portion of the wrapper covering this end of At the same time the punch 23 penetrates the wrapper and-filler and causes portions of the wrapper in contact with the punch to be forced into the outer end of the bore which is thereby formed in the filler.

In Fig. 5 I have shown a portion of a cigar having the mouth end bored in accordance with this invention. In this view 45 designates the bore which is formed in the filler by the punch 23 and 46 designates that portion of the wrapper which is tuckedinto the outer end of the bore.

From the foregoing it will be apparent that the apparatus-described herein provides a simple and efficient medium whereby the punching of the wrapper and the filler to provide a smoke or draft bore and the tucking in of the wrapper at the outer end of the bore are conveniently accomplished in a single op eration. I

Having thus described my invention, what I claim is:

1. The combination with a rotary cigar end knurling device of a punch, and means cigar wrapper and filler to form a smoke or draft passage in the filler during the knurling operation.

2." A rotary cigar end knurling device equipped with a punch mounted thereon and adapted tofpenetrate the cigar wrapper and filler to form a draft passage in the end of the cigar engaged by the knurling device, said punch being tapered toward its pointed end to force the punched portion of the wrap per intothe outer end of the draft passage as the punch penetrates the filler.

3. The combination of a rotary cigar end knurling'device, a punch mounted on said knurling device and adapted to penetrate the 'cigarwrapper and filler at the end engaged with said knurling device, acigar sup. port mounted in front oftheknurling device in spaced relation thereto, said supportaf fordinga rest for "the cigar during the. operation of pushing it into engagement with the knurling device anda tubular cigar-centering member mounted between the knurling device and the adjacent end of the support in a position to ensure proper centering of the cigarwith respect to theknurling' device and the punch as it is advanced into engageinent therewith. 4:. The combination of a rotary cigar end knurlingdevice mounted to rotateabout a horizontal axis, a centered punch mounted on the knurling device adapted to penetrate the cigar wrapper and filler at the end engaged with said knurling, device, a horizontal. cigar support mounted in front of the knurling device at a suitable level to supportthe cigar during the operation of advancing it into engagement with said knurling device, a tubularcigar centering member normally disposed in a. horizontal position between the support andthe knurling device toensure proper centering of the cigar duringits advance into engagement with the knurling device and the punch carried by the knurling device, and meansmount-ing said centering member for swinging movement toan inoperative position.
